Unsteady boundary layer flow of a Casson fluid past a wedge with wall slip velocity

In this paper an analysis is presented to understand the effect of non–Newtonian rheology, velocity slip at the boundary, thermal radiation, heat absorption/generation and first order chemical reaction on unsteady MHD mixed convective heat and mass transfer of Casson fluid past a wedge in the presence of a transverse magnetic field with variable electrical conductivity. The partial differential...

Hypersonic Boundary Layer Analysis Comparison of Velocity Measurements and Monte-carlo Calculations

The study of gas-solid accommodation at low pressure is of paramount importance to several areas of scientific research and industrial development. In Chemical Vapor Deposition (CVD) processes for instance, ONERA has quantified the accommodation for several diatomicsolid pairs and shown that, near or below 100 Pa, the gas can be substantially colder than the surface being grown, at a distance l...

Measurements of streamwise and spanwise fluctuating velocity components in a high Reynolds number turbulent boundary layer

Measurements of the streamwise and spanwise fluctuating velocity components are obtained in a high Reynolds number turbulent boundary layer using custom made sub-miniature hot wires. These measurements are made over a range of Reynolds numbers from Reτ ≈ 3,000 to Reτ ≈ 10,500, but at fixed unit Reynolds number U∞/ν (Reτ = δUτ/ν; where ν is the kinematic viscosity, Uτ is the friction velocity an...

Velocity and Temperature Measurements in a Natural Convection Boundary Layer Along a Vertical Flat Plate

T. Tsuji Y. Nagano Department of Mechanical Engineering Nagoya Institute of Technology, Nagoya, Japan l lA turbulent natural convection boundary layer along a vertical flat plate in air is investigated with hot-wire techniques. Profile measurements of mean velocity, mean temperature, and turbulent quantities, which are obtained well into the wall region, clarify some characteristics peculiar to...
